    Purpose of use
    Interest piqued by Big Bang Theory episode in which Sheldon proclaims Sir Isaac Newton was born on Christmas Day if measured by the Julian calendar. I have the same birthday, and wished to determine if mine, too, was on December 25 Julian. Sadly, I am a little younger than Sir Isaac, so no.
